====== Encoder Tables in C Applications ======


===== makefile =====

Add the "-DDONT_INCLUDE_MIOS_ENC_TABLE" define:
<code make>
# pass parameters to MIOS wrapper
MIOS_WRAPPER_DEFINES = -DSTACK_HEAD=0x37f -DSTACK_IRQ_HEAD=0x33f \
                       -DDONT_INCLUDE_MIOS_ENC_TABLE
</code>

===== main.c =====

Add your table as such:
<code c>
/////////////////////////////////////////////////////////////////////////////
// Application specific encoder table
// the default (dummy) table has been disabled via -DDONT_INCLUDE_MIOS_ENC_TABLE
/////////////////////////////////////////////////////////////////////////////
MIOS_ENC_TABLE {
             // sr pin mode
  MIOS_ENC_ENTRY(1, 0, MIOS_ENC_MODE_DETENTED2),
  MIOS_ENC_EOT
};
</code>

===== Reference =====

Taken from mios wrapper

<code asm>
;; ---[ configuration table for rotary encoders ]---
#ifndef DONT_INCLUDE_MIOS_ENC_TABLE
;; dummy table located in $MIOS_PATH/include/asm
;; If the application should use ENC entries,
;; just add "-DDONT_INCLUDE_MIOS_ENC_TABLE" to MIOS_WRAPPER_DEFINES
;; and build the table within the C program with:
;;
;; MIOS_ENC_TABLE {
;;              // sr pin mode
;;   MIOS_ENC_ENTRY(1, 0, MIOS_ENC_MODE_DETENTED), // VPot #1
;;   MIOS_ENC_ENTRY(1, 2, MIOS_ENC_MODE_DETENTED), // VPot #2
;;   MIOS_ENC_ENTRY(1, 4, MIOS_ENC_MODE_DETENTED), // VPot #3
;;   MIOS_ENC_EOT
;; };
;;
;; The MIOS_MT_* macros are defined in $MIOS_PATH/include/c/cmios.h
#include <mios_enc_table.inc>
#endif
